5. Pressure at the top: 1.01 X10 Pressure at the bottom: 1.99 ×105 a. If the block is a cube, what is the force on the block due to the water (buoyant force)? b. What, then, is the weight of the block? What is the density of the block? c. Another method: How much (what percentage) of the block is submerged? Check that the density of the block is that same percentage of the density of water (1000 kg/m³). Specific gravity, s.g = Pblock/Pwater Now consider what would happen if we put the block in an oil with a different density. d. Predict what you expect will happen if we put the block in an oil with a density of 700 kg/m³. e. Try it. Was your prediction correct? Explain.
